The SDC AUTO Series Architectural Automatic Door Opener is a commercial low-energy swing door operator designed for applications requiring ADA accessibility, automatic pedestrian access and user convenience. The operator combines a state-of-the-art microprocessor-based control system with a quiet belt-driven mechanical design for dependable operation in commercial and institutional entrances.
The SDC AUTO Series is self-tuning, self-learning and nonhanded, providing installation flexibility for push/outswing and pull/inswing commercial doors. Full mechanical stops and multiple interface options allow the operator to work with compatible sensors, push plates, fire alarm systems and electrified locking hardware.
Unlike conventional direct-drive designs, the SDC operator utilizes a belt-driven combination of gears and pulleys. This design requires less torque and power, helps absorb abuse and provides exceptionally quiet automatic door operation.
One of the defining features of the SDC AUTO Series is its belt-driven operating system. The operator utilizes a combination of gears and pulleys engineered to provide smooth and quiet movement while reducing the amount of torque and power required to operate the door.
The belt-driven design also helps absorb abuse encountered in commercial entrance applications. This makes the SDC AUTO Series an attractive choice for facilities where quiet operation, smooth door movement and dependable commercial performance are important.
The SDC AUTO Series is designed for low-energy ADA automatic door applications and complies with applicable U.S. and Canadian accessibility requirements for low-energy automatic operators.
A compatible knowing-act activation device, such as a handicap push button, wireless push plate or touchless actuator, can signal the operator to begin the automatic opening cycle. Opening speed, closing speed and hold-open time can be adjusted for the requirements of the entrance.
Appropriate automatic door signage is included with the operator.
The SDC AUTO Series incorporates a state-of-the-art microprocessor-based controller designed to simplify setup and operation. Self-tuning and self-learning functionality allows the operator to establish operating parameters for the entrance while providing adjustment options for specific installation requirements.
Onboard diagnostics simplify troubleshooting and help technicians identify operational conditions during installation, adjustment and service.
The SDC AUTO Series is nonhanded and can be configured for surface-mounted push or pull applications. This provides flexibility for commercial doors with different handings and swing directions.
